Slate roofing-paint



UNITED STATES PATENT OFFICE.

JACOB L. FAUSS, OF NORTH BRISTOL, ASSIGNOR OF ONE-HALF TO EDWARDS W. LAIRD, OF CLEVELAND, OHIO.

SLATE ROOFING-PAINT.

SPECIFICATION forming part of Letters Patent No. 240,899, dated May 3, 1881.

Application filed May 8, 1880. (Specimena) .To all whom it may concern Be it known that I, JACOB L. FAUSS, of North Bristol, in the county of Trumbull and State of Ohio, a citizen of-the United States, and residing at the above-named place, have inventedanew and useful composition of matter to be used for painting or coating roofs, of which the following is a specification.

I use in this composition the residue of coaltar after distillation, of benzole, and dead or stale oil therefrom, the first distillate from coal-tar, called crude benzole or spirits of coal-tar, and the second or last distillate from coal-tar, called dead or stale oil, and

ground hematite ore, and ground slate. The

first three ingredients are obtained from the refining of coal-gas tar. The other two in gredients are obtained by grinding or pulverizin g common hematite ore and common slate, such as is usedin slate-roofing. These ingredients I use in the proportions as follows of the residue of coal-tar, three parts 5 of ground hematite ore, two parts of ground slate, one part; of dead-oil or crude carbolic acid, three parts; of crude benzole, three parts.

The manner of preparing my composition is as follows: I place the residue in a vessel over a fire just long enough to warm' and melt it sufficient to mix readily; then I add the pulverized ore and slate and thoroughly mix them together by stirring, I then add the other ingredients-the crude benzole and dead-oil-to reduce to the proper consistency to enable it to be spread readily with a brush, the crude benzole acting as a drier.

it is to render it hard rather than to melt it.

It does not melt and run off, like ordinary tar and gravel roofing neither does it make the water which falls from a roof having it on taste of the tar.

The great advantage this posesses is that y it can be prepared and used any time thereafter without heating, which is not the casewith other mixtures containing coal-tar.

What I claim, and desire to secure by Letters Patent of the United States, is--- The herein-described composition of matter to be used for coating roofs, consisting of residue of coal-tar, ground hematite ore, ground slate, crude benzole, and dead or stale oil or crude carbolic acid, in the proportions specified.

J. L. FAUSS.
